Name: Ephedra aspera Shrubland
Reference: NatureServe Biotics 2019
Description: This joint-fir shrubland association is currently described from Grand Canyon National Park in Arizona. More survey and classification work are needed to fully characterize this type. It typically occurs on sideslopes at 750 to 1100 m (2425-3225 feet) elevation, but can be found as high as 1650 m (5350 feet). It is primarily found on moderate to steep (20-40°), north- to east-facing slopes, but also occasionally occurs on gentler slopes (8-15°). Soils are well- to rapidly-drained silty or sandy loams that occasionally contain clay. Vegetation is characterized by the dominance of <i>Ephedra aspera</i> in the short-shrub stratum. Tall shrubs are rare and sparse, but <i>Acacia greggii</i> is occasionally present as either a tall or short shrub. The short-shrub layer also includes <i>Bernardia myricifolia</i>. <i>Gutierrezia sarothrae</i> is a common dwarf-shrub. <i>Muhlenbergia porteri, Vulpia octoflora</i>, and <i>Aristida purpurea</i> are fairly common in the graminoid understory. The non-native <i>Bromus rubens</i> also occurs in most stands. <i>Acourtia wrightii, Galium stellatum, Sphaeralcea grossulariifolia</i>, and <i>Erodium cicutarium</i> (exotic) are common components of the forb understory.
